Incinerator Company, Milwaukee,

Application August 26, 1940, Serial N03 354,203 1 Claim. (c1, 110-18) This invention relates generally to incinerators, and more particularly to the ready built type, either portable or installed in building walls for burning refuse and garbage. I

The invention has primarily for its object to provide means for increasing the combustion efficiency of conventional incinerators.

Incidental to the foregoing, a more specific object of the invention resides in the provision of a novel structure of head for the top of an incinerator, designed to admit and heat air for combustion, and discharge the same downwardly towards the refuse contained in the combustion chamber of the housing.

Another object of the invention resides in the provision of a hollow headin communication with outside atmosphere, and having an arrangement of partitions for directing admitted air over a circuitous route to discharge openings in the bottom of the head, whereby the air is heated to increase combustion.

A still further object resides in the provision of an incinerator head having dischargenozzles arranged to direct air for combustion in a downward spiral path.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the novel construction, combination, and arrangement of parts, substantially as hereinafter described, and more particularly defined by the appended claim, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.

In the accompanying drawings is illustrated K one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.

In the drawings:

Figure 1 is a fragmentary perspective View of an incinerator, incorporating the present invention;

Figure 2 is a fragmentary vertical section, taken on the line 2-2 of Figure 3;

Figure 3 is a plan view of the head plate with its cover removed, and detached from the incinerator housing;

Figure 4 is a. similar view of a modified form of head plate; and

Figure 5 is an enlargeddetailsection, taken on the line 5-5 of Figure 4.

Referring now more particularly to the accompanying drawings, the numeral I designates a housing provided with a refractory lining 2. Positioned in the front wall of the housing is a frame structure 3, which carries the usual filling door 4 and other doors (not shown), providing access to the interior of the incinerator.

Mounted upon the top of the housing I, and v secured thereto in any suitable manner is a hollow head designated generally by the numeral 5, and comprising a plate 6 having an upwardly extending peripheral wall 1. The top of the plate 6 is closed by a layer of insulating material 8, and a cover 9 having depending side walls iii overlapping the housing I.

As best shown in Figures 1, 2, and 3, the plate 6 is provided with a central opening ll, surrounded by a vertical sleeve l2 for reception of the usual breaching connecting the incinerator with a flue. Adjacent the front edge of the plate 6 is a depending transverse flange i3, spaced from the front wall "1' of the plate to form an ,air passage I4 communicating with the interior.

of the plate through spaced openings l5. and with outside atmosphere through the admission openings 15. Central partitions ll, extending between the end walls and the sleeve l2, serve to divide the plate into separate compartments [8.

In addition to the foregoing, each compartment I8 is provided with a partition 20, the front end H of which is connected with an adjacent side wall 1, while the rear end 22 terminates in spaced relation to the rear peripheral wall. Spaced discharge openings 23 are provided in the plate 6 in the areas between the peripheral walls and the partitions 20.

From the foregoing explanation considered in connection with the accompanying drawings, it is thought that the operation of the invention will be readily apparent, in that due to the flue draft through the opening 4 I, outside air is drawn into the head of the passage I l; and, as indicated by the arrows on Figure 3, the same will travel rcarwardly and around the ends 22 of the partitions 25, to be discharged downwardly through the openings 23. els over the circuitous paths defined by the partitions I! and 2t, and the sleeve 12, the same becomes heated through contact with the plate,

which serves as the top of the combustion chamber C. Inasmuch as an increase in the temperature of air supplying combustion advances the rate of combustion, maximum eiiiciency of the combustion operation is obtained.

In that form of the invention disclosed in Figures 4 and 5, a circular plate 6' is provided for attachment to a cylindrical housing (not shown).

Due to the fact that combustion is advanced with 7 Obviously, as air trav- I increased turbulence of air, and maximum mixing with combustible gases,in this form of the invention, it is proposed to provide the plate 6' with depending nozzles 24 surrounding the dis-' charge openings 23, to provide directed jets of air travelling in a downward helical path ad jacent the periphery of the circular housing. The

cylindrical column of air thus created surrounds and contacts a central column of combustible" gases, and'through progressive'mixingwitn the gases, serves tofacilitate secondary combustion v while that portion of air reaching the refuse aids primary combustion. v p

From the foregoing, it will be apparent that an exceedingly simple and inexpensivelde'vice has 6. been provided, which introduces outsideair of increased temperature to efiect maximum combustion, thereby materially incre ciency of the incinerator.
